These batteries worked fine. I had use another kind of battery, but I was getting an error message, so I ordered these batteries and I have not had any problems at all.

Seem to work just fine.

NeE zero charge or current

When the batteries on the Comcast wall mount security keypad needed replacement, I was lucky enough to find Battery Junction who made the process from identifying, selecting, ordering and installing very easy. First, they have a portion of their business devoted to Comcast devices. They show pictures of the different devices so you can compare it to yours, then provide the batteries to order. When the package arrived, there were even directions with pictures on how to open and install the batteries. I don't think the entire process could have been simpler.

Ordered and package arrived within 2 days, price is competitive with big box stores without the driving and locating in the store. Took all of a minute to replace old batteries and install new.
